The voucher was exchanged for the ferry tickets, I was directed to the ferry passenger entrance.
The ferry departed and arrived at it's destination on time
Ordered a trip from Chaweng to Donsak for 500thb. There was a confusion on their part but they resolved it in time. We got a van to the pier + ferry to Donsak
Booked the fast catamaran, only takes 50 mins, don’t book the ferry, it takes 2 to 3 times longer. Yes it’s cheaper on the ferry but it’s worth the extra for convenience. Make sure you arrive 20-30 mins before as you have to walk to the end of the pier (5min) walk after you checkin.
Great boat ride, well worth it!
